F5 GTM Subdelegation
I am practicing sub delgeation exercise in the lab, in my DNS server I am delegating subdomain wip.domain.com to the F5 devices, current zone file for domain.com: $TTL 604800 @ IN SOA domain.com. admin.domain.com. ( 57 ; Serial 900 ; Refresh 15 mins 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; ; name servers - NS records IN NS ns1.domain.com. IN NS ns2.domain.com. ; name servers - A records ns1.domain.com. IN A 192.168.242.200 ns2.domain.com. IN A 192.168.242.201 www.domain.com. IN CNAME www.wip.domain.com. wip.domain.com. IN NS gtm1.wip.domain.com. wip.domain.com. IN NS gtm2.wip.domain.com. gtm1.wip.domain.com. IN A 10.10.4.50 gtm2.wip.domain.com. IN A 172.16.14.50 In the F5 GTM device I created a wideip - www.wip.domain.com - this works returning the relevant A record. Now I noticed when I created this, a zone was created in zonerunner "this.name.is.invalid" which creates a default NS/SOA and A record (pointing to 127.0.0.1). What is the correct process that must be done further? since any NS queries etc which are polled to the GTM respond with "this.name.is.invalid" - should I update zonerunner with the subdomain zone records, I tried to do this from https://support.f5.co/csp/article/K35603050 but adding a second nameserver in the zone failed (gtm2.wip.domain.com). - or should I create a primary/secondary nameserver on the GTM's for the subdomain? Thank you in advance
